在光學系統，可以利用光子晶體來吸收特定波段的波長，而使其他波長的光通過，因此我們想設計一材料，使材料在頻率熱源時有類似光子晶體的特性。
在光子晶體中，是用兩種折射率不同的材料所組成，所以我們設計的材料是由兩種物質所堆疊而成，可以讓特定頻率的熱源通過，而其他頻率的熱源不能通過。而在本研究著重於分析與討論，以及建立理論預測的模型。
本論文以有限元素分析法模擬與解析探討，各種不同的結構溫度的比較，最後並透過有限元素分析軟體COMSOL驗證我們理論及方法的正確性。

A analogy between optical and thermal propagation in heterogeneous anisotropic media had been proposed recently. All thermal parameters are related to optical ones in artificial metallic media, thus making possible to use numerical codes developed for optics.
Our develops and analyzes a metamaterial for heat dissipation. Similar photonic crystal, some frequency of photonic can penetrate, another frequency of photonic can’t penetrate. Electromagnetic and heat diffusion simulations based on the finite element method (FEM) are accomplished to verify that the design of the proposed film. A decrease of frequency can be achieved high penetration rate.
